How can I easily sort by campaign, which emails have been opened and not

I’m looking for a way to keep tabs on which emails have been opened and which ones are still unopened. Thanks - John

You can have an automation link call an action set that raises a tag in the legacy email builder but the new builder doesn’t allow you to inject code necessary to do so. The open rate isn’t very accurate metric as most clients immediately register as open when the preview shows the email and that may or may not mean it was opened.

Thank you.
